We present a spatially resolved analysis of the temperature and gas density profiles of galaxy clusters at z=0.4-0.7 observed with XMM-Newton. These data are used to derive the total cluster mass within the radius r₅₀₀without assuming isothermality and also to measure the average temperature and total X-ray luminosity, excluding the cooling cores. We derive the high-redshift M-T and L-T relations and compare them with the local measurements. The high-redshift L-T relation has low scatter and evolves as L∝(1+z)^1.8±0.3 for a fixed T, in agreement with several previous Chandra and XMM-Newton studies (Vikhlinin et al., Lumb et al., and Maughan et al.). The observed evolution of the M-T relation follows M₅₀₀∝E(z)^–α, where we measure α=0.88±0.23. This is in agreement with predictions of the self-similar theory, α=1.
