AbstractIn this work, superconductivity with a maximum superconducting transition onset temperature T-C of 3.6K is reported in La1-xSmxCo2B2 in the concentration range 0.12 <= x <= 0.20. Substitution of magnetic Sm ions with 4f electrons for La is beneficial for superconductivity in the system. The low upper critical field of La0.8Sm0.2Co2B2 suggests that the dominant magnetic-field suppressing superconducting mechanism is the orbit pair-breaking effect. A special specific-heat anomaly is observed around TC. (C) 2015 AIP Publishing LLC.
