Effects of external magnetic field and orbital degeneracy on the spin fluctuationsin weakly ferromagnetic ntetals are studied based on the recent self-consistentlyrenormalized spin fluctuation theory to obtain expressions for the spin fluctuationcontributions to the nuclear magnetic relaxation rate 1/T. and the specific heat.By using these expressions and taking account of the orbital relaxation contribu-tion, our experimental data of the temperature and magnetic field dependences of1/T. for "Zr in ZrZnz are well interpreted and are analysed semtvi-quantitativelyvieldins useful informations on the electronic structure of ZrZn.. The spinfluctuation contribution to the specific heat at low temperatures in ZrZn. is alsoestimated.
