Title: Magnetic Structures of HoCoO<sub>3</sub> and TbCoO<sub>3</sub>
Abstract: Abstract The magnetic behavior of HoCoO 3 and TbCoO 3 has been studied from magnetic measurements and neutron diffraction experiments performed on polycrystalline samples. The magnetic measurements indicate that the Co 3+ ions exhibit a low‐spin electronic configuration t 2g 6 e g 0 with S = 0 below room temperature. The neutron diffraction data show that HoCoO 3 and TbCoO 3 order with an antiferromagnetic structure below T N = 3 and 3.6 K, respectively. The magnetic structure for HoCoO 3 and TbCoO 3 are given by the basis vectors ( A x ,0, C z ) and ( C x ,0, A z ), respectively. Therefore, the magnetic moments are in the (010) plane. At T = 1.5 K, the ordered magnetic moments of Ho 3+ and Tb 3+ ions are 6.48(4) and 7.86(4) μ B , respectively.
