Abstract

Magnetic order of HoB4 with Shastry-Sutherland-type Ho lattice has been studied by neutron diffraction. In HoB4, two magnetic phase transitions take place at TN 1 = 7.1 K and TN 2 = 5.7 K. Below TN 1, the intensity of the magnetic satellite reflection described by Q = (± δ ± δ ± δ) with δ = 0.022 and δ = 0.424 gradually increases together with the weak intensity of the (1 0 0) magnetic reflection. Below TN 2, the intensity of the (1 0 0) reflection steeply increases like a first-order transition and the satellite reflection disappears. These magnetic phase transitions are similar to those of HoB2 C2 in which the rare-earth ions form a square lattice without geometrical frustration.
