Abstract： The behavior of magnetoresistance in thin silver films was investigated from 1.8 up to 104 K. Weak localization effect, manifested by negative magnetoresistance, remains until 88 K in magnetic fields below 2T. Experimental results indicate that weak localization theory for two-dimensional disordercd systems is applicable even when the phase relaxation length L is a few times longer than the elastic mean free path l, provided L is larger than the thickness of films. The obtained phase relaxation time τ obeys 1/T2.6 law.
