Metamagnetism, giant negative magnetoresistance and spin glass state in the Sm1-xSrxMnO3 (x=0.33, 0.45) and RE0.55Sr0.45MnO3 (RE0.55 = Eu0.397Nd0.153, Tb0.25Nd0.30) manganites as well as in the CuCr2X4 (X = S, Se) spinels doped with Sb

The experimental evidence of metamagnetism, giant negative magnetoresistance and spin glass state is presented for the compounds under study. An attempt is made to explain the jump-like phase transition of the colossal negative magnetoresistance of -4433% at 153.2 K into the colossal positive magnet...
