_{3}(M=Ti, V, Cr, Mn, Fe, Co, Ni, Cu), one member (SrNiO

_{3}) is missing. In this paper we use GGA+U method based on density functional theory to examine its properties. It is found that SrNiO

_{3}is a ferromagnetic half-metal. The charge density map shows a high degree of ionic bonding between Sr and other atoms...

_{3}. A series of hypothetical strains on SrTcO

_{3}are considered to simulate its being applied in SrTcO

_{3}-based devices. It is found that a tensile strain will decrease T

_{N}, while a compressive strain less than 6.6% will increase T

_{N}. At a...

_{3}are examined by means of the density functional theory calculations with on-site Coulomb interaction corrections to Ru 4d electrons. A robust magnetic ground state for SrRuO

_{3}is found even when its volume is compressed to a value close to the experimental volume of the nonmagnetic (NM) CaRuO

_{3}. Nevertheless,...

_{3}and CaTcO

_{3}. G-type antiferromagnetic (G-AFM) is found to be ground state for both compounds, in consistence with the previous experimental results. The mechanism of Neel temperature of SrTcO ...

_{3}are calculated by means of the generalized gradient approximation (GGA) plus on-site Coulomb interaction corrections (GGA+U) method. G-type antiferromagnetic (G-AFM) is found to be ground state, in consistence with the previous experimental result. The distortions around Sr and Tc upon magnetic transition are compared and the change of...

_{3}in ground state is obtained from the generalized gradient approximation (GGA) with on-site Coulomb correction (GGA+U) calculations (U=3.4 eV, J=0.49 eV ), which agrees with the experimental result very well. A series of local spin density approximation (LSDA) with on-site Coulomb corrections (LSDA+U) and GGA+U calculations are performed with various U and J parameters...

_{3}are studied from first principles calculations within the generalized-gradient approximation (GGA) framework. The orthorhombic structure with AFM1 configuration (see Fig. 1) is found to be the ground state of SrMnO

_{3}, consistent with the latest experimental observation. The orthorhombic distortion effect of SrMnO

_{3}is...
