ABSTRACT
Superconductors are materials with zero electrical resistivity and the ability to expel magnetic fields, which is known as the Meissner effect. Their dissipationless diamagnetic response is central to magnetic levitation and circuits such as quantum interference devices. In this work, we used superconducting diamagnetism to shape the magnetic environment governing the transport of spin waves-collective spin excitations in magnets that are promising on-chip signal carriers-in a thin-film magnet. Using diamond-based magnetic imaging, we observed hybridized spin-wave-Meissner-current transport modes with strongly altered, temperature-tunable wavelengths and then demonstrated local control of spin-wave refraction using a focused laser. Our results demonstrate the versatility of superconductor-manipulated spin-wave transport and have potential applications in spin-wave gratings, filters, crystals, and cavities.
ABSTRACT
The traditional role of hospital pharmacists in drug analysis and drug compounding broadened to a patient-oriented approach during the sixties and seventies. The clinical pharmacy concept was adopted. This practice includes daily-prepared total parenteral nutrition and chemotherapy, sophisticated analgesic systems, individualized drug distribution and specific information. The hospital pharmacy provides aseptic procedures as well as specialized logistics. Clinical pharmacy practice concentrates on tailor-made pharmaceutical care. As home health care usually deals with therapeutic modalities, this approach offers great possibilities for highly skilled out-patient care. Financial and legal interferences and the traditional gap between in-patient care and out-patient care must be removed. Home health care challenges the hospital pharmacists to place his knowledge and abilities at the disposal of this new type of patient care.
