Magnetoelectric Cr_2 O_3 and relativity theory
Friedrich W. Hehl, Yuri N. Obukhov, Jean-Pierre Rivera +1
Relativity theory is useful for understanding the phenomenology of the magnetoelectric effect of the antiferromagnet chromium sesquioxide Cr_2 O_3 in two respects: (i) One gets a c…
Relativistic analysis of magnetoelectric crystals: extracting a new 4-dimensional P odd and T odd pseudoscalar from Cr_2 O_3 data
Friedrich W. Hehl, Yuri N. Obukhov, Jean-Pierre Rivera +1
Earlier, the linear magnetoelectric effect of chromium sesquioxide Cr_2 O_3 has been determined experimentally as a function of temperature. One measures the electric field-induced…
Relativistic nature of a magnetoelectric modulus of Cr_2O_3-crystals: a new 4-dimensional pseudoscalar and its measurement
Friedrich W. Hehl, Yuri N. Obukhov, Jean-Pierre Rivera +1
Earlier, the magnetoelectric effect of chromium sesquioxide Cr_2O_3 has been determined experimentally as a function of temperature. One measures the electric field-induced magneti…
Commensurate-Incommensurate Magnetic Phase Transition in Magnetoelectric Single Crystal LiNiPO
D. Vaknin, J. L. Zarestky, J. -P. Rivera +1
Neutron scattering studies of single-crystal LiNiPO reveal a spontaneous first-order commensurate-incommensurate magnetic phase transition. Short- and long-range incommensurate…
