We have measured the specific heat and magnetization up to 50 T of polycrystalline samples of RCrTiO $_{5}$ (R=Pr, Nd, Eu, Sm and Gd) and also carried out powder neutron diffraction experiments of NdCrTiO $_{5}$ and Nd $_{0.5}$ Pr $_{0.5}$ CrTiO $_{5}$ . 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 $^{3+}$ - Cr $^{3+}$ magnetic moments and between the Cr $^{3+}$ -R $^{3+}$ ones. The temperature dependence of neutron magnetic reflection intensities of NdCrTiO $_{5}$ indicate that both the Cr $^{3+}$ -moments and the Nd $^{3+}$ -moments simultaneously order at $T_mathrm{N}$ . Basis of the obtained magnetic behavior, the mechanism of magnetoelectric effect of RCrTiO $_{5}$ will be discussed.
