Ernst F. R. A. Schloemann
of Weston, Massachusetts died on March 2, 2003 at the Lahey Clinic in Burlington, Massachusetts after a six month illness with melanoma. He was 76 years old.

Ernst Schloemann has been a preeminent researcher and scholar in the broad field of magnetism and magnetic materials, with a strong but not exclusive emphasis on ferrites and microwave processes. Dr. Schloemann was one of the first scientists to propose and develop a theoretical framework for two magnon scattering microwave relaxation processes in ferrites. He also developed the first comprehensive theory of

parallel pumping, a nonlinear process for the parametric excitation of spin waves with a microwave field parallel to the static field. His far reaching work in magnetism has spanned many other areas as well, from the basic theory of loss processes and excitations in magnetic materials, to thin films, microwave device applications, and magnetic separation, among others. Dr. Schloemann was a Fellow of the American Physical Society, a Fellow of the Institute of Electrical and Electronic Engineers (IEEE), and a member of Sigma Xi.

Ernst Schloemann was born in Borgholzhausen, Germany on December 13, 1926. He graduated from the University of Goettingen in the Federal Republic of Germany with a Bachelor of Science degree in Physics in 1951, a Master of Science Degree in 1953, and a Ph. D. degree in 1954. After graduation, Dr. Schloemann came to the United States as a Fulbright Fellow at the Massachusetts Institute of Technology in Cambridge, Massachusetts. In 1955 he began his career with Raytheon Corporation as a staff scientist at the Raytheon Research Division located in Waltham, Massachusetts. He became a Research Fellow at Raytheon and was the recipient of the Raytheon T. L. Phillips Award for Excellence in Technology in 1990. Dr. Schloemann retired from Raytheon in 1995 but continued vigorous research work as a consultant and participated in numerous international conferences and research programs up to the time of his death. Ernst Schloemann was an avid windsurfer and champion squash player. He was a member of the Longfellow Sports Club in Sudbury, Massachusetts and the Massachusetts Squash Racquets Association.

A resident of Weston, Massachusetts since 1960, Dr. Schloemann was married to Gisela Mattiat up until her death in 1990. They had been married for 35 years. He is survived by his second wife of 9 years, Sally Duren Schloemann of Weston, three daughters, a brother and sister, and five grandchildren. Dr. Schloemann is interred at the Linwood Cemetery in Weston.
