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 NdPrCrTiO. 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.
