I. CREANGA1,*
Magnetic properties and magnetocaloric effects were studied in GdxLa1-xNi5 compounds. The Curie temperatures decrease from TC = 35 K in GdNi5 to 9K for a sample with x = 0.2. The maximum entropy changes, in field of H = 7 T, vary from 12.8 J/kgK (x=1.0) to 5.5 J/kgK (x = 0.2). In high external field, linear dependences of the maxima in the entropy changes on H2/3 were shown as expected for compounds which show a second order type magnetic transition. The relative cooling power in field of 7 T, decreased from 347 J/kg (x = 1.0) to 80 J/kg (x = 0.2)..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
