Sažetak
M-H loops for virgin and neutron irradiated bulk and powder samples of MgB_2 were measured in the temperature range 5-30 K in magnetic field B<1T. The irradiation oat thermal neutron fluences 9x10^13 and 4.5x10^14 cm^-2 caused very small enhancement of m-H loops at lower temperatures (T<20K), whereas the effect at high temperatures was nuclear due to the difficulty in achieving exactly the same measurement temperature prior and after irradiation.
