    LLEVAREMOS A CABO, LA SINTESIS QUIMICA, LA CARACTERIZACION FISICA Y EL DISEÑO TEORICO DE MOLECULAS MAGNETICAS DE INTERES EN ESPINTRONICA CUANTICA, INCLUYENDO LA COMPUTACION CUANTICA. ESTAS TAREAS SE RETROALIMENTARAN: LOS AVANCES TEORICOS QUE RELACIONEN ESTRUCTURA MOLECULAR CON CAMPO CRISTALINO Y COMPORTAMIENTO CUANTICO DE LOS ESTADOS DE ESPIN FACILITARAN LA SINTESIS DE NUEVOS COMPUESTOS CON MEJORES PROPIEDADES; LA SINTESIS DE ESTOS COMPUESTOS PERMITIRA SU ESTUDIO EXPERIMENTAL, Y ESTOS DATOS NOS AYUDARAN A REFINAR LOS MODELOS TEORICOS. EN LA ETAPA FINAL, SE PREPARARAN Y ESTUDIARAN DISPOSITIVOS MOLECULARES._x000D_ _x000D_ DE ENTRE LOS DIFERENTES SISTEMAS QUIMICOS QUE SE EMPLEARAN DESTACAN LOS POLIOXOMETALATOS, CAPACES DE (A) ENCAPSULAR ESPINES LOCALIZADOS EN FORMA DE IONES LANTANIDOS Y (B) ALOJAR ESPINES DESLOCALIZADOS, CUANDO ESTAN EN FORMA DE VALENCIA MIXTA. EL INTERES DE LOS COMPLEJOS DE LANTANIDOS EN ESTE CONTEXTO, SEAN O NO DE POLIOXOMETALATOS, ES SU CAPACIDAD PARA FORMAR MOLECULAS-IMAN DE UN SOLO CENTRO (IONES-IMAN) Y QUBITS DE ESPIN MOLECULARES. COMPLEMENTARIAMENTE, ESTUDIAREMOS COMO AFECTA A UN ION-IMAN LA PRESENCIA DE UN RADICAL ORGANICO PROXIMO. PARA FACILITAR ESTE ESTUDIO, SE PREPARARAN Y CARACTERIZACION_x000D_ _x000D_ COMPUESTOS ANALOGOS EN DIFERENTE ESTADO DE OXIDACION, ESTO ES, ACTIVANDO Y DESACTIVANDO EL RADICAL. LAS MOLECULAS DE VALENCIA MIXTA, POR SU LADO, Y DE NUEVO SEAN O NO POLIOXOMETALATOS, PERMITEN EL CONTROL DE SU ESTADO ELECTRICO Y MAGNETICO MEDIANTE CAMPOS ELECTRICOS, LO QUE LAS HACE RELEVANTES PARA LA ESPINTRONICA MOLECULAR COMO INTERRUPTORES MOLECULARES CONTROLADOS ELECTRICAMENTE. _x000D_ _x000D_ LA CARACTERIZACION FISICA, MAS ALLA DE DETERMINAR LA MAGNETIZACION O LA SUSCEPTIBILIDAD MAGNETICA, INCLUIRA MEDIDAS DEPENDIENTES DEL TIEMPO COMO EXPERIMENTOS LANDAU-ZENER PARA ESTUDIAR CRUCES EVITADOS E INTERFERENCIA CUANTICA. SE ENSAYARA TAMBIEN LA MANIPULACION COHERENTE DE VARIOS DE LOS COMPUESTOS SINTETIZADOS MEDIANTE EPR PULSADO (EN CONCRETO, ELECTRON SPIN ECHO ENVELOPE MODULATION O ESEEM Y ELECTRON-NUCLEAR DOUBLE RESONANCE O ENDOR). EL ESTUDIO DE LOS NANODISPOSITIVOS SE LLEVARA A CABO MEDIANTE EL METODO CONOCIDO COMO "BREAK JUNCTION"._x000D_ _x000D_ FINALMENTE, SE MEJORARAN SUSTANCIALMENTE LOS MODELOS TEORICOS EXISTENTES. SE MEJORARA LA CAPACIDAD DE NUESTRO PROGRAMA SIMPRE PARA LA PREDICCION DE IONES-IMAN CON LA PARAMETRIZACION DE LOS LIGANDOS HABITUALES EN LA QUIMICA DE LANTANIDOS EN FORMA DE CARGAS EFECTIVAS. ADICIONALMENTE, SE TENDRA EN CUENTA DE FORMA EXPLICITA EL ACOPLAMIENTO ESPIN-ORBITA. FINALMENTE, SE INCLUIRAN EN EL HAMILTONIANO TERMINOS DE ACOPLAMIENTO ENTRE EL LLAMADO "ESPIN CENTRAL" Y SU ENTORNO, EN FORMA DE BAÑO DE ESPINES Y BAÑO DE OSCILADORES. ESTO PERMITIRA RACIONALIZAR LAS MEDIDAS FISICAS Y FACILITARA EL DISEÑO DE NUEVOS COMPUESTOS. (Spanish)

    WE WILL CARRY OUT CHEMICAL SYNTHESIS, PHYSICAL CHARACTERISATION AND THEORETICAL DESIGN OF MAGNETIC MOLECULES OF INTEREST IN QUANTUM SPINTRONICA, INCLUDING QUANTUM COMPUTATION. THESE TASKS WILL BE FED BACK: THEORETICAL ADVANCES RELATING MOLECULAR STRUCTURE TO CRYSTALLINE FIELD AND QUANTUM BEHAVIOUR OF THE ESPIN STATES WILL FACILITATE THE SYNTHESIS OF NEW COMPOUNDS WITH BETTER PROPERTIES; THE SYNTHESIS OF THESE COMPOUNDS WILL ALLOW THEIR EXPERIMENTAL STUDY, AND THESE DATA WILL HELP US TO REFINE THEORIC MODELS. In the final stage, they will be prepared and studied MOLECULARY DISPOSITIVES._x000D_ _x000D_ BETWEEN THE CHEMIC DIFFERENT SYSTEMS that will be used DISCOUNT THE polyoxomethalates, CAPACES OF (A) encapsular SPINES LOCALISED IN FORM OF lantanid ions AND (B) Alocate delocalised SPAINS, when they are in MIXTA VALENCE FORMA. THE INTEREST OF LANTANID COMPLEXES IN THIS CONTEXT, WHETHER OR NOT POLYOXOMETHALATES, IS THEIR ABILITY TO FORM SINGLE-CENTER MAGNET MOLECULES (IMAN IONS) AND MOLECULAR SPINE QUBITS. IN ADDITION, WE WILL STUDY HOW IT AFFECTS AN ION-IMAN THE PRESENCE OF AN ORGANIC RADICAL NEXT. To FACILITATE THIS STUDY, Prepared AND CHARACTERISATION_x000D_ _x000D_ COMPOSES Analogs IN DIFFERENT OXIDATION STATE, THIS IS, ON and deactivating RADICAL. THE MOLECULES OF MIXED VALENCIA, ON THEIR SIDE, AND AGAIN WHETHER OR NOT THEY ARE POLYOXOMETALATES, ALLOW THE CONTROL OF THEIR ELECTRICAL AND MAGNETIC STATE BY ELECTRIC FIELDS, WHICH MAKES THEM RELEVANT TO MOLECULAR SPINTRONICA AS MOLECULAR SWITCHES CONTROLLED ELECTRICALLY. _x000D_ _x000D_ the PHYSICAL CHARACTERISATION, MORE TO DETERMINATE magnetisation OR MAGNETIC susceptibility, shall include DEPENDENT MEASURES OF THE TIME as LANDAU-ZENER EXPERIMENTS TO STUDY Avoided CRUCS AND QUANTIC INTERFERENCE. THE CONSISTENT MANIPULATION OF SEVERAL OF THE COMPOUNDS SYNTHESISED BY PULSED EPR (E.G. ELECTRON SPIN ECHO ENVELOPE MODULATION OR ESEEM AND ELECTRON-NUCLEAR DOUBLE RESONANCE OR ENDOR) WILL ALSO BE TESTED. The status of the nanodevices will be carried out by means of the known metal as “BREAK JUNCTION”._x000D_ _x000D_ FINALENT, SUSTANCIALLY THE EXISTENT TEORIC MODELS will be improved. THE CAPACITY OF OUR PROGRAM WILL BE IMPROVED FOR THE PREDICTION OF ION-IMAN WITH THE PARAMETRISATION OF THE USUAL LIGANDS IN THE CHEMISTRY OF LANTANIDS IN THE FORM OF EFFECTIVE LOADS. IN ADDITION, THE ESPIN-ORBITA COUPLING WILL BE EXPLICITLY TAKEN INTO ACCOUNT. FINALLY, THE HAMILTONIAN TERMS OF COUPLING BETWEEN THE SO-CALLED “CENTRAL SPIN” AND ITS SURROUNDINGS, IN THE FORM OF A SPINE BATH AND OSCILLATOR BATH, WILL BE INCLUDED. THIS WOULD MAKE IT POSSIBLE TO RATIONALISE PHYSICAL MEASURES AND FACILITATE THE DESIGN OF NEW COMPOUNDS. (English)
