(a,b) Temperature dependence of pyroelectric current J(T), and electric polarization P(T) of NTO-b determined from the integration of J(T) with respect to time at μ H=1, 8.5 and 9 T, respectively. (c,d) Magnetic field dependence of magnetization M(H) and dielectric constant ɛ(H) of NTO-a at various temperatures for both increasing and decreasing magnetic fields. A black dashed line in c depicts linear fit to M(H) curve for H>Hc and at T=47 K.
