with the gagarinite-type structure (NaCaYF

). Magnetic susceptibility
c
was measured with the
aid of the Faraday balance in the temperature range from 20 to 300 K. The crystals with
R
= Dy, Ho, Er, Tm are
paramagnetic; their temperature dependence
c
is described by the Curie–Weiss law. It is shown that in the temperature
range studied, magnetic susceptibility does not depend on the degree of order of Dy, Ho, Er, and Tm
ions in the structure. Below 80 K, the temperature dependence of magnetic susceptibility of the the Yb
3+
- containing
phases differs from the analogous dependence
c
of an ideal paramagnetic crystal, which is assumed to
be caused by the interaction of the crystalline field with Yb
3+
ions.
