Perovskite-like bulk La1/3Nd1/3Ca1/3MnO3 is prepared by solid phase reaction method. The temperature dependence of the magnetization and the relationship between CMR effect and sintering have been studied. The CMR is up to 673.9% under 1 T applied magnetic field and 100 K temperature, and that also reaches 93.5% in 0.2 T and 100 K.

The total ribbon voltage of as-quenched and annealed Fe96-xZrxB4 (x=7 or 10) ribbons has been measured as a function of applied de field and drive current frequency. The experimental results show that both samples exist the optimum annealing temperature and optimum frequency at which the relative change in ribbon voltage is strongest, and the sensitivity of the magnetic response of the annealed Fe89Zr7B4 ribbon is two order of magnitude larger than that of the annealed Fe86Zr10B4 ribbon. The effect of magnetic properties and structural characteristics on giant magneto-impedance was discussed.
