“…16, 5.74, 19.95, 55, 61, 70, 90, 92, 100 and 115. These results are close to the data of spectroscopic studies of Ho 3þ in KGd(WO 4 ) 2 single crystal [16], where D i are equal to 6,11,22,48,75,120,163,188,209 and 229.…”

“…A very low-temperature phase transition to an antiferromagnetic state is the characteristic property of these low-symmetry systems and indicates that the exchange interactions are weak. For example, the Neel temperature values of T N are equal to 0.6, 0.7, 0.82, 0.85 and 1.34 K for KDy(WO 4 ) 2 , KTb(WO 4 ) 2 , RbDy(WO 4 ) 2 , KEr(WO 4 ) 2 and CsDy(WO 4 ) 2 , respectively [6,[9][10][11][12].…”

“…In singlet magnets, an unusual magnetic behaviour is expected and it is difficult to predict the emerging and character of magnetic ordering. The criterion for the appearance of a magnetically ordered state in a singlet magnet in two-level singlet-singlet approximation is the relation |I|4, where I is the exchange integral and the energy gap [11]. In the KHo(WO 4 ) 2 crystal, the distance between two lowest singlets and higher energy levels far exceeds I [11].…”

The results of measurements of thermal properties (specific heat) of potassium holmium double tungstate KHo(WO 4 ) 2 as a function of temperature (from 0.5 to 300 K) and magnetic field (up to 2 T) are presented. The total specific heat without the phonon and Schottky contributions is found to have the anomaly with maximum at T SPT $ 5 K. This anomaly is likely related with the structural phase transition (SPT) caused by the cooperative Jahn-Teller effect. The increase of specific heat at very low temperatures and its shift towards high temperatures with increasing magnetic field are observed. The origin of this behaviour can be connected with possible magnetic phase transition induced by magnetic field.

The magnetic investigations of potassium holmium double tungstate KHo(WO 4 ) 2 have been performed. The results of measurements of magnetic susceptibility and magnetization as a function of temperature (T from 0.3 K up to 100 K) and magnetic field (up to 1.5 T) are presented. A strong anisotropy of magnetic properties was found. The magnetic measurements data were used to calculate the interaction energy. It was shown that the interactions between nearest neighbors Ho 3+ ions have antiferromagnetic character.
