Abstract

The magnetic ordering transitions in spin-ice candidate material Ho ₂Ru₂O₇, which reveals two magnetic transitions at T ∼95 and ∼1.4K to long-range ordered states, were analyzed. A commercial SQUID magnetometer was used to measure magnetic properties between 2 and 600 K. Although there was short-ranged ordered state on Ho³⁺ sites well above 1.4K, it was found that Ru⁴⁺ ordering was enough of a perturbation of fragile spin-ice state to induce ordering upon Ho³⁺ site and drive system to order. The results show that Ho³⁺ ordering found in Ho₂Ru₂O₇ is due to small internal field produced by the Ru⁴⁺ ordering.
