Magnetic Resonance Force Specialist Zurich Instruments Acquired by Rohde & Schwarz
Building its portfolio for swooping on big opportunity in quantum
computing, German test and measurement company Rohde &
Schwarz has acquired Zurich Instruments, a developer of magnetic
resonance force microscopy systems. Zurich's magnetic
force lock-in amplifiers and its sophisticated signal generators
are considered important tools for researchers needing precision
test and measurement solutions in the fast-growing field.
Zurich will operate as a wholly owned subsidiary with all functions
to remain in place, from development and production
to marketing and sales. " The size, stability and technological
expertise of Rohde & Schwarz offer optimal conditions for us to
remain a leader in the rapidly growing quantum computing market
and continue to grow as an independent subsidiary, " said
Dr. Sadik Hafizovic, co-founder and CEO. He is shown above
with other key managers, from left, Adrian Messmer, VP R&D
and HR; Flavio Heer, CTO; Hafizovic; Jan Benhelm, CMO; and
Stephan Koch, VP Sales.
" We are looking forward to developing technological solutions
for the future together with Zurich Instruments, " said Peter Riedel,
president and COO of Rohde & Schwarz. " Our customers
can expect further innovations in lock-in amplifiers, impedance
test and measurement instruments and quantum computing
control systems. "
In the coming decades, quantum technologies will significantly
shape the high-tech industry, he noted. " The potential for
industry and research is enormous. It is a future trend involving
billions in governmental subsidies and industrial investment.
Rohde & Schwarz is already active in quantum sensing. Thanks
to the acquisition, the company is now positioning its T&M solutions
in quantum computing, one of the most promising future
technologies in the world. "
Based in Zurich, Switzerland and now with about 100 staff, Zurich
was founded in 2008 as a spin-off from the Swiss Federal
Institute of Technology (ETH Zurich). Its instruments can be
used for Hall Effect sensing and magnetic materials characterization
with applications including quantum and nano electronics,
low-temperature physics and transport measurements.
Three years ago, it introduced the first commercial quantum
computing control system, designed to control more than 100
superconducting and spin qubits.

As illustrated in the figure above, MFLI differential measurements
of the voltage induced in the VSM pick-up coils generated
by a periodically oscillating sample magnetized in a homogeneous
magnetic field. The vibration frequency of the VSM is
provided by the lock-in amplifier and the signal is demodulated
at the same frequency. With Cryogenic VSM magnetometers
the temperature dependence of magnetization can be measured
as well as the magnetization behavior at a fixed temperature
where for ferromagnetic materials a hysteresis loop reveals
information on magnetization saturation, coercive field and
anisotropy. The sample is placed in the center of the pick-up
coil configuration.

In a recent webinar, application scientist Jelena Trbovic,
who manages nanotechnology and magnetism applications,
explains how magnetic materials can be characterized using
Zurich's magnetic force lock-in amplifiers. The webinar,
which along with a blog is available on the company's website,
covered two basic magnetic characterization techniques, vibrating
sample magnetometry (VSM) and AC susceptibility where
lock-in amplifiers are essential part of the measurement and the
detection chain.
