MOLECULAR ELEMENT WITH MAGNETIC FIELD RESPONSE, MAGNETIC FIELD MEASURING METHOD AND MAGNETIC FIELD MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a molecular element that has high sensitivity and responsiveness to faint magnetic field and low magnetic field, and to provide magnetic field measuring technology using the same.;SOLUTION: The molecular element displays conductivity when it is optically excited, and its charge recombined fluorescence or electric resistance varies even by application of magnetic field. When the intensity B of applied magnetic field is reduced under an irradiating light with optionally predetermined intensity, the fluorescent intensity variation rate R to magnetic field represented by the following formula shows a minimum value or a maximum value Rm in a magnetic field Ba of limited intensity excluding zero, and when it is reduced furthermore, the R increases or decreases and it becomes zero in the zero magnetic field. R=[Φ(B)-Φ(0)]/Φ(0) where, Φ(B): fluorescent emission intensity or resistance when the intensity of magnetic field is B under the irradiating light with predetermined intensity; Φ(0): fluorescent emission intensity or resistance in zero magnetic field under the same irradiating light.;COPYRIGHT: (C)2009,JPO&INPIT
