STATIC MAGNETIZATION OF KAPPA-(BEDT-TTF)(2)CU[N(CN)(2)]CL UNDER HIGH-PRESSURE .2. LOW MAGNETIC-FIELD

Low-field measurements have revealed the presence of paramagnetic cont ribution to the field-cooled magnetization of single crystal of title salt at pressures as high as 1 kbar and 1.5 kbar. This magnetization a ppears if field is oriented normal to the conducting ac plane, at temp erature just below the onset of bulk SC transition, and saturates at f ields of a few Oe. Depending on thermal history, it can even dominate over the diamagnetic Meissner signal. This behavior is similar to rece ntly discovered (due to study of HTSC oxides), intensively studied but still remaining not understood Wohlleben effect (or paramagnetic Meis sner effect). For the kappa-(BEDT-TTF)(2)Cu[(CN)(2)]Ce that the coexis ting magnetic phase might be a cause for the phenomenon.
