Abnormal Diamagnetic Respond in Co_0.2Mn_1.7Sn Compound

Abstract:

The Co-doped Co_0.2Mn_1.7Sn compound was prepared by melting appropriate metals with purity higher than 99.9% in a magneto-controlled arc furnace. The compound shows single-phase characteristics. Magnetic measurements show that, the abnormal negative magnetization, i.e. diamagnetism occurs at low temperature. Moreover, it displays the common weak ferromagnetism, together with some spin-glass-like behavior. Besides, we conjure that abnormal negative magnetization should be from the magnetized sample when cooling the compound in the so-called zero field (in fact it is about 2.5×10^-5 T).
