  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 r_500 without
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\pm0.3}
for a fixed T, in good agreement with several previous Chandra and XMM-Newton
studies (Vikhlinin et al., Lumb et al., Maughan et al.). The observed evolution
of the M-T relation follows M_500 = A T^{3/2} E(z)^{-alpha}, where we measure
alpha=0.88\pm0.23. This is in good agreement with predictions of the
self-similar theory, alpha=1.
