High magnetic field scanning probe microscope employing liquid helium-free room-temperature bore superconducting magnet

A microscope system, comprising:

• a scanning probe microscope including a scanning head and a vacuum chamber;
• and
• a superconducting magnet defining a room-temperature bore, the room-temperature bore accommodating the scanning head and at least a portion of the vacuum chamber;
• wherein there is no direct physical contact between the scanning probe microscope and the superconducting magnet.

A microscopic system, comprising:
