WebBloch introduced two relaxation time constants, which he called T1 and T2, to account for the reestablishment of thermal equilibrium of the nuclear magnetization after generation of the NMR signal. T1 reflected the regrowth of longitudinal magnetization ( M z ), whereas T2 characterized the decay of the transverse components ( M x and M y ). WebThe TRM response can be exploited in completely reversible bipolar switching performances either by tuning the temperature only across a sharp thermal window T w= 10 K, or annealing isothermally with a single pulse of eld 0.1 T by ipping the direction of magnetization from 0oto 180o.
