Disappearance of Quasi-Ising Character in Triangular Lattice Antiferromagnet CuFeO_2 by a Small Amount of Substitution(Condensed Matter : Electronic Structure, Electrical, Magnetic and Optical Properties)

概要
- 論文の詳細を見る
The effect of a small amount of substitution on magnetic ordering in a frustrated triangular lattice antiferromagnet CuFeCO_2 has been studied by neutron diffraction, magnetic susceptibility and specific heat measurements on CuFe_<1-x>Al_xO_2 single-crystals with x=0.02 and x=0.05. With only a small amount of substitution, x=0.02, the zero-field successive magnetic phase transitions with quasi-Ising character observed for x=0.00 are entirely changed to successive phase transitions from a paramagnetic state to an incommensurate complex state through an incommensurate magnetic state, suggesting that the original Heisenberg spin character hidden in CuFeO_2 is retrieved.
