We have measured the specific heat and magnetization up to 50 T of polycrystalline samples of RCrTiO (R=Pr, Nd, Eu, Sm and Gd) and also carried out powder neutron diffraction experiments of NdCrTiO
and Nd
Pr
CrTiO
. From the analyses of specific heat data and magnetization curves up to 50 T of the systems, we have evaluated the magnetic interactions between the Cr
- Cr
magnetic moments and between the Cr
-R
ones. The temperature dependence of neutron magnetic reflection intensities of NdCrTiO
indicate that both the Cr
-moments and the Nd
-moments simultaneously order at
. Basis of the obtained magnetic behavior, the mechanism of magnetoelectric effect of RCrTiO
will be discussed.
